TLV2634IPW from UMW, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	1OUT	output	Amplifier 1 output. Rail-to-rail output, capable of sourcing/sinking ~28 mA at Vdd=5 V (short-circuit ~95 mA).
2	1IN-	input	Amplifier 1 inverting input. High-impedance CMOS input (>=1000 GOhm differential, ~12 pF Ccm, IB ~1 pA typ).
3	1IN+	input	Amplifier 1 non-inverting input. Common-mode input range GND to Vdd-1 V.
4	VDD	power_in	Positive supply. Single-supply range 2.7 V to 5.5 V (absolute max 6 V); split supply +/-1.35 V to +/-2.75 V. Bypass close to the pin.
5	2IN+	input	Amplifier 2 non-inverting input. Common-mode input range GND to Vdd-1 V.
6	2IN-	input	Amplifier 2 inverting input. High-impedance CMOS input.
7	2OUT	output	Amplifier 2 output. Rail-to-rail output.
8	3OUT	output	Amplifier 3 output. Rail-to-rail output.
9	3IN-	input	Amplifier 3 inverting input. High-impedance CMOS input.
10	3IN+	input	Amplifier 3 non-inverting input. Common-mode input range GND to Vdd-1 V.
11	GND	power_in	Device ground / negative supply reference. For single-supply operation, tie to 0 V.
12	4IN+	input	Amplifier 4 non-inverting input. Common-mode input range GND to Vdd-1 V.
13	4IN-	input	Amplifier 4 inverting input. High-impedance CMOS input.
14	4OUT	output	Amplifier 4 output. Rail-to-rail output.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlv2634ipw.step`	194 KB	You want the bare part, or you mark your own boards.
`tlv2634ipw-etched.step`	2.1 MB	You want the part with `TLV2634IPW` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 544 faces against 237 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
